对四川金榜路招生计划的数据爬虫获取

调试分析

首先登录到该网站，点击下面的招考数据->招考计划。当我们想对下面的大学招生计划数据进行获取时，打开F12进行调试

没看见我们想要的大学内容，唯一一条可疑数据是这样的：

js AES 256位加密 js加密怎么破_js逆向

从它的返回内容中可以看出，数据返回data, encry:true，encry一般是加密的意思，返回数据说明对内容进行了加密，那么我们接下来就是分析js，找到加密的算法

找到JS

应该怎么查找这个JS呢，首先从加密这里进行解密，加密的关键字一般都是encry,或者encrypt，所以我们可以尝试全局搜索encry, 最终在app的js中找到这样的一段js

直接就得到了这样可疑的JS，这时候我们应该大胆猜测。

AesEncrypt.可以知道这里就是AES的加密函数，其中密钥key是m1x2!3p4 $js AES 256位加密 js加密怎么破_js逆向_04$ ，偏移量iv是1234567890000000

接下来再打个断点调试一下，在这里的encry打上断点

再按下F11进去，发现到了解密函数这里，然后我们执行下，可以看到最终返回的结果就是我们需要的大学信息

进行解密

看看这个js的解密时怎么样的
最终的这个r呢，是s.toString()得来，而s呢就是AES的对i的解密算法
i 是对a进行base64得来，a呢又是对t进行Hex得到的
那么我们的思路就得到了，只需要按照这段js对返回内容进行解密即可
首先对网站进行请求，返回的是一段16进制的字符串，对16进制的字符串进行Hex(), 在对结果进行Base64,最后解密

python实现

简单的写一个python来实现

def decrypt(text, key, mode):
    cryptor = AES.new(key, mode, b'1234567890000000')
    plain_text = cryptor.decrypt(base64.b64decode(text))
    print(plain_text.decode('utf8'))
    return plain_text

if __name__ == '__main__':
    import base64
    from Crypto.Cipher import AES
    from binascii import b2a_hex, a2b_hex
    key = b'm1x2!3p4$567890000000123456789@$'
    mode = AES.MODE_CBC
    t =
